Deterministic Sentence Counter & Segmentation Analyzer
Sentence count is a core indicator of document density and pacing. Too few sentences in a long text indicates dense, run-on prose, while too many short sentences can make writing feel disjointed.
This tool accurately segments sentences using punctuation-aware tokenization that distinguishes actual sentence endings from common abbreviations, decimal numbers, and initials. Inspect overall sentence counts, averages, and individual sentence structures.
Core Tool Capabilities
- Abbreviation-Aware Segmentation: Accurately identifies sentence boundaries while ignoring periods in titles (Dr., Mr.), abbreviations (e.g., i.e.), and numbers.
- Average Length Analytics: Calculates average words and characters per sentence across your entire document.
- Shortest & Longest Detection: Highlights the most concise and most verbose sentences for editorial review.
- Searchable Sentence Table: Browse individual sentences in a structured table with live keyword filtering.

Frequently Asked Questions
- How does the tool avoid false sentence splits on abbreviations?
- The segmentation engine references a built-in abbreviation corpus (including titles like Dr., Mr., time indicators like a.m., p.m., and Latin abbreviations like e.g., i.e.) to prevent false breaks.
- Does the tool support question marks and exclamation points?
- Yes. Sentences terminated by periods, exclamation marks, question marks, or ellipsis followed by whitespace are properly segmented.
- Can I export the list of individual sentences?
- Yes. Clicking 'Download Report (TXT)' exports a structured text file containing document metrics and a numbered list of all individual sentences.
- Is my text private?
- Yes. Everything runs client-side in your browser.
